摘　　要：研究了以碘作氧化剂、4-氨基安替比林（4-AAP）分光光度法测定水中的挥发酚，方法的检出限为1ug/L，线性范围为2—24g／L，相关系数为0．9995。条件优化后，方法的精密度为3．5％，加标回收率为91．3％-118．0％，方法的精密度和准确度均符合要求。The experiment of detecting volatile phenol in water by 4-aminoantipyrine spectrophotometry and iodine as oxidizer showed that the limit of detection was 1 ug/L, and the linear range was 2.0 -24.0 ug/L, r =0.9995. After the experiment factors were optimized, the precision of the method was 3.5% , and the recoveries of standard addition was 96.3% - 106%. The precision and accuracy of experiment meet the requirement.
